If you're looking for a 29" mountain bike that won't break the bank, the Nashbar AT1 29er mountain bike should be your first choice. The steel hardtail 29er MTB frame is incredibly durable and has excellent trail feedback. The Shimano 7-speed drive train provides more than enough gears to give you plenty of speed on the flats and still power up the hills with ease. The 29" wheels allow you to roll over some pretty gnarly singletrack with ease. It's an incredibly affordable 29" mountain bike that's ready to rock as is, or perfectly ready for some upgrades if you're in the market for a project bike.

I am a large guy, and need a big bike that is durable, and I am not a high mileage user, so I don't need an expensive bike, just one that is durable and attractive. This is the PERFECT bike for me. I like it so much, I just purchased a smaller AT1 for my partner that is arriving in September (to replace a worn out IRONHORSE.)

Sadly, we are both without bikes now, as the AT1 I just bought is not yet here, and both my AT1 29-er and the Ironhorse were just stolen. Unfortunately after just paying for the other AT1, I don't have funds to replace my 29-er. I will absolutely be saving for a replacement soon. Miss my red beast.

I use this to get to work, and for exercise, recreation. The set up was very easy (I am exp. in bike repair/maintenance) the wheels came true, much to my surprise, brakes, shifting only needed minor adjustments. As a low income person, who has owned much more expensive bikes in the past, I was very skeptical of this price, I really figured the only thing I would keep is the frame, and wheels, I had intended to replace all the components, and I will, but the ones it comes with are fine, and really a casual rider wouldn't need to change a thing. If you are looking for an entry level 29'r, this is a good basic model that can be relatively easily upgraded, up to a point. I have put about 500 miles on it already, and I love it. I don't think I will use it for hard-core MTB, but for everything else, it is just right. The only reason it does not get 5 stars is that it is a entry level bike, and I am picky, however, it could get a 5 star for its price and quality (for the price).

I was looking for a cheap steel 29er and when i was thinking i would not get... i got it!

All components are cheap and you can not expect shiftness or great performance on mtb trails, but frame looks like well-made, nice geometry for mtb rides (73.5° seat, 71.5° headset, 445 chainstay, big slooping).

If you want a serious bike for mtb, you will need to change chainrings, square taper (too wide 122.5, better 117.5), seatpost (too short and heavy) and stem+handlebar. If you want to conmuting, it comes perfect.

Rear wheel has give me some problems on the cog, and i had to lace again using longer spokes. Shifters are not perfect for mtb, but works fine. Tires are not recommended for mtb use, no grip on curves or braking.

For a rookie rider or a guy tired from carbon, alloy ultralight and ultratech over the bikes, this can be the perfect one.

I have two of these now. I love the steel frame and after a few changes it is everything I Want in an all around bike. One is set up more for distance riding the other for dirt trails. I did change a few things but not because I had to. I sold my 800.00 plus bike and had a few extra dollars to buy the parts I changed on it. I didn't need to but wow is this bike good now.

Purchased because of price. Assembled easy and was surprised with the ride. I changed derailleurand shifters for trigger style. Now I really loved the bike. So I decided to buy a better quality 29er. I did and found I now missed my sold Nashbar 29er. I bought another AT-1 the same size and changed out the same parts when putting it together and it also rides great. Now I'm selling my really expensive 29er because I love this bike. Steel is real and ride is better.

I bought this bike for the purpose of converting it into an electric bike with a rear-wheel hub motor. I specifically wanted a steel 29er frame with rear rack mounts. I had to find an adapter for the upper rack attachment but there are options out there. I ended up getting what is called a monostay adapter and it fits perfectly under the seatpost clamp. It was nice that the fork has a caliper mount for a disc brake upgrade, even though I did have to buy a new front wheel with a rotor attachment on the hub. Overall, the bike works great for my purpose and it's awesome to cruise to work at 20+ mph for under a penny/mile of electricity.

It rides a lot better than it looks like it would. The components look cheap but work pretty good. I bought this bike as a spare for friends to ride so they never have the excuse "I don't have a bike" LOL

Bought this for my son to take to college, so I didn't have to whine when his Rocky Mountain got stolen. Bike is solid, but extremely heavy. Needs a setback seatpost to fit..........I think anyone correctly. Downside is, the seatpost is 25.4 for some reason, not 27.2. Looks like I'm going to have to find a BMX seatpost somewhere. Bizarre size for an MTB seatpost.

My Parks and Recreation Department just extended the local bike path to within 300 meters of my house. No more excuses - time to start exercising! The 21" frame/29" wheel combination are made for big guys like me. The components are of reasonable quality and from brand manufacturers. For the price, it was equipped better than anything else on the market. Customer Service was extremely helpful and assembly was fairly easy. One loose screw on the chain guard was my only hiccup.

I've owned three Nashbar bikes since the 1990's (which have been passed down to the next generation). Good, quality products. It was time to get some newer technology in my garage and take advantage of our community's new greenway - where else would I go to shop?
